From stabilisation to stagnation. Viktor Yanukovych's reforms. OSW Point of View Number 32, March 2013

After winning the 2010 presidential election, Viktor Yanukovych and his government developed an ambitious and comprehensive programme of reforms across key areas of social and political life. The return to a presidential system of government created the ideal conditions for the introduction of deep reforms: it allowed Viktor Yanukovych to consolidate more power than any other Ukrainian president before him.The authorities launched an overhaul of the tax and the pension systems, and of the Ukrainian gas sector. Kyiv also completed its negotiations on an Association Agreement with the EU and on a Deep and Comprehensive Free Trade Area. However, the reformist zeal of Ukraine’s political elite progressively diminished as the parliamentary election approached, the economy slowed down, and the polls showed a decline in support for the ruling Party of Regions. Many of the reforms still remain in the planning stages, and in many areas the government has moved backwards. Viktor Yanukovych has proved unable to make systemic changes, and has increasingly used his powers to crush political opposition in Ukraine. The outcome of the latest parliamentary elections prevents the formation of a stable parliamentary majority, which in turn, removes any chance of reform before the 2015 presidential ballot.

On the periphery of global jihad. The North Caucasus: the illusion of stabilisation. OSW Point of View Number 45, November 2014

The situation in the North Caucasus has stabilised, in comparison with previous years, mainly as regards the activity of the Islamic military underground. This is an effect of ideological changes among the militants which have led to a dilution of the Caucasian armed struggle and its marginalisation in global jihad, since top priority has been granted to the Middle Eastern front. The factors which have contributed to this stabilisation are the organisational crisis in the Caucasus Emirate and the outflux of militants to the Middle East, as well the successful ‘carrot and stick’ policy adopted by Moscow. However, the partial stabilisation in the Caucasus is inherently precarious, being a contingent outcome of the situation rather than the result of systemic change. The region’s pressing problems remain unresolved; and these problems are generating chronic instability and cauing the Caucasus to drift away from Russia in civilisational terms. An economic or political crisis in the Russian Federation may result in the conflicts in the Caucasus unfreezing, including a reactivation of the idea of Chechen independence as well as the idea of the Caucasus Emirate, which is a part of global jihad.

Paradoxes of stabilisation. Bosnia and Herzegovina from the perspective of Central Europe. OSW Report, March 2016

On 15 February 2016 Bosnia and Herzegovina applied for membership of the European Union. This was the result of the new policy strategy which the EU introduced in 2014, aimed at unblocking BiH’s integration process and encouraging local elites to accelerate the reform process. Despite a formal application to the EU, the main internal problems of BiH remain the same - local politicians focus more on the power struggle and enhancing ethnic division than on reform and this is hampering the economic development of one of the poorest countries in Europe. For these reasons this report is devoted to analysing the internal challenges to the stability, coherence and unity of the country. Special attention was also placed on examining the interest and strategies of the various international actors since they can hinder or support the reform process.

Characterizing the physical and chemical properties of a vermicompost filter bed

Vermicompost filtration is a new on-site waste treatment system. Consequently, little is known about the filter medium properties. The aim of this preliminary study was to quantify physical and compositional properties of vermicompost filter beds that had been used to treat domestic solid organic waste and wastewater. This paper presents the trials performed on pilot-scale reactors filled with vermicompost from a full-scale vermicompost filtration system. Household solid organic waste and raw wastewater at the rate of 130 L/m(2)/d was applied to the reactor bed surface over a four-month period. It was found that fresh casts laid on the bed surface had a BOD of 1290 mg/g VS while casts buried to a depth of 10 cm had a BOD of 605 mg/g VS. Below this depth there was little further biodegradation of earthworm casts despite cast ages of up to five years. Solid material in the reactor accounted for only 7-10% of the reactor volume. The total voidage comprised of large free-draining pores, which accounted for 15-20% of the reactor volume and 60-70% micropores, able to hold up water against gravity. It was shown that water could flow through the medium micropores and macropores following a wastewater application. The wastewater flow characteristics were modeled by a two-region model based on the Richards Equation, an equation used to describe porous spatially heterogeneous materials.

Manufacture of high pressure die-cast radio frequency filter bodies

The manufacture of a radio frequency filter box using high pressure die casting (HPDC) is compared to the traditional high speed machining route. This paper describes an industrial exercise that concluded HPDC to be an economical and appropriate method to produce larger volumes of thin-walled telecommunications components. Modifications to the component design were made to make the component suitable for the HPDC process. Development of the die design through simulation modelling is described. The wrought alloy was replaced by near-eutectic Al-Si die casting alloy that was found to give better temperature stability performance. Apart from the economic benefits, HPDC was found to give lower filter efficiency losses through better surface finish. The effects of HPDC process variables, such as intensification pressure and injection piston velocity, on component quality, particularly porosity levels, were investigated. The pressure was analysed in terms of HPDC machine set pressure and the pressure measured in the die cavity by pressure sensors. Porosity was found to decrease with increased pressure and slightly increase with higher casting velocities.

Quantitative photoluminescence of broad band absorbing melanins: a procedure to correct for inner filter and re-absorption effects

We report methods for correcting the photoluminescence emission and excitation spectra of highly absorbing samples for re-absorption and inner filter effects. We derive the general form of the correction, and investigate various methods for determining the parameters. Additionally, the correction methods are tested with highly absorbing fluorescein and melanin (broadband absorption) solutions; the expected linear relationships between absorption and emission are recovered upon application of the correction, indicating that the methods are valid. These procedures allow accurate quantitative analysis of the emission of low quantum yield samples (such as melanin) at concentrations where absorption is significant. (c) 2004 Elsevier B.V.

Attachment insecurity as a filter in the decoding and encoding of nonverbal behavior in close relationships

In this article, I have focused my comments on the possible associations between the cognitions related to different attachment styles, and the impact that those cognitions are likely to have on nonverbal encoding and decoding. I see attachment insecurity as acting as a filter, distorting both encoding and decoding processes. In terms of decoding, an insecure individual may appraise the situation as more threatening than it actually is, may see the attachment figure as more or less available than he or she actually is, and may make an inappropriate decision about the viability or desirability of seeking proximity to the attachment figure. Attachment insecurity is also likely to inhibit the distressed individual from expressing their distress in a way that is understood by the attachment figure and that increases the likelihood that the attachment figure will engage in supportive behavior.

Mutations within the selectivity filter of the NMDA receptor-channel influence voltage dependent block by 5-hydroxytryptamine

Background and purpose: Voltage-dependent block by Mg2+ is a cardinal feature of NMDA receptors which acts as a coincidence detector to prevent the receptor from over-activation. Inhibition of NMDA receptor currents by 5-hydroxytryptamine (5-HT) indicated that 5-HT, similar to Mg2+, binds within the membrane electric field. In the present study, we assessed whether point mutations of critical asparagine residues located within the selectivity filter of NR1 and NR2A subunits of NMDA receptor-channel affect voltage-dependent block by 5-HT. Experimental approach: The mode of action of 5-HT and Mg2+ on wild-type and mutated NMDA receptor-channels expressed in Xenopus oocytes was investigated using the two-electrode voltage clamp recording technique. Key results: The mutation within the NR1 subunit NR1(N0S or N0Q) strongly reduced the voltage dependent block by 5-HT and increased the IC50. The corresponding mutations within the NR2 subunits NR2A(N0Q or N + 1Q) reduced the block by 5-HT to a lesser extent. This is in contrast to the block produced by external Mg2+ where a substitution at the NR2A(N0) and NR2A(N + 1) sites but not at the NR1(N0) site significantly reduced Mg2+ block. Conclusion and implications: The block of NMDA receptor-channels by 5-HT depends on the NR1-subunit asparagine residue and to a lesser extent on the NR2A-subunit asparagine residues. These data suggest that the interaction of 5-HT with functionally important residues in a narrow constriction of the pore of the NMDA receptor-channel provides a significant barrier to ionic fluxes through the open channel due to energetic factors governed by chemical properties of the binding site and the electric field.
